Description
FIELD OF THE INVENTION
[0001] The present invention relates to an electrical connector,
and more particularly to an electrical connector, which is easily
manufactured, and which has additional structure to support the
bending and transition portions of the shielding cover of the
electrical connector.
BACKGROUND OF THE INVENTION
[0002] Electrical connectors are widely applied for electrically
connecting electrical components for facilitating assembly and
disassembly between the electrical components. Different
requirements correspond to electrical connectors with different
functions. Regarding an electrical connector for high frequency and
high-speed signal transmission, the energy of electromagnetism
radiation is largely increased due to the increasing of working
frequency, it is important to shield electromagnetism interference
produced by the signal transmission, and the electrical connector
is often provided with a shielding cover for shielding
electromagnetism interference.
[0003] Referring to FIG. 5, a prior art electrical connector,
includes a shielding cover 100, a dielectric housing 200 fitted in
the shielding cover 100, and a plurality of conductive terminals
300 inserted in the dielectric housing 200. The shielding cover 100
includes a top wall 102, two side walls 104 bending downward from
the top wall 102 and two bottom walls 106. The two side walls 104
of the shielding cover 100 are bent downward to form two pairs of
bending and transition portions 108, 110 having different
configurations, wherein the rear bending and transition portions
110 are formed by substantively vertical bending, while the front
bending and transition portions 108 are formed by slantedly bending
a certain angle.
[0004] However, the two pairs of bending and transition portions
108, 110 of the shielding cover 100 of the prior art electrical
connector are in different configurations. Such an unsymmetric
structure causes relative difficulty and inconvenience for
manufacturing a punch model and processing the electrical
connector. Additionally, the front bending and transition portions
108 are suspended and are not supported by a support member,
thereby they are easily deformed after repeated insertion with and
withdrawal from a mating connector.
SUMMARY OF THE INVENTION
[0005] Accordingly, an object of the present invention is to
provide an electrical connector, two pairs of bending and
transition portions of a shielding cover thereof are easily
manufactured due to being adopted with a symmetric structure having
an identical configuration.
[0006] Another object of the present invention is to provide an
electrical connector, two sides of a dielectric housing thereof are
additionally provided with two support portions for supporting the
bending and transition portions, so that the bending and transition
portions are not easily deformed after repeated insertion and
withdrawal.
[0007] To fulfill the above-mentioned objects, an electrical
connector of the present invention includes a shielding cover, a
dielectric housing and a plurality of conductive terminals. The
shielding cover includes a top wall, two sidewalls bending downward
from two sides of the top wall respectively, and a bottom wall
further bending from each of the two sidewalls of the shielding
cover. The dielectric housing includes a vertical wall, and a
bottom plate extending outwardly from the vertical wall in a
direction toward a mating connector. The bottom plate has at least
one support portion projecting upwardly from a side of the bottom
plate. The shielding cover also includes at least one pair of
bending and transition portions in an identical configuration
formed between one of the two sidewalls and the bottom wall of the
shielding cover. The support portion of the dielectric housing is
located directly below the bending and transition portions to
prevent the bending and transition portions from being deformed.
Other features are optionally included on the electrical connector
of the present invention.
[0008] The electrical connector of the present invention adopts two
pairs of bending and transition portions of the shielding cover in
an identical configuration with a symmetric structure, so that the
shielding cover is easily manufactured. Furthermore, the two
support portions of the dielectric housing support the bending and
transition portions of the shielding cover from the below, to
thereby prevent the bending and transition portions from being
deformed as a result of repeated insertion and withdrawal with a
mating connector.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENT
[0015] While the invention may be susceptible to embodiment in
different forms, there is shown in the drawings, and herein will be
described in detail, a specific embodiment with the understanding
that the present disclosure is to be considered an exemplification
of the principles of the invention, and is not intended to limit
the invention to that as illustrated and described herein.
[0016] Referring to FIGS. 1 to 4, an electrical connector of the
present invention may be used for an interface of a high definition
multimedia, which includes a shielding cover 2, a dielectric
housing 4 and a plurality of conductive terminals 6.
[0017] The shielding cover 2 is integrally formed by punching and
bending from a metal piece, and is formed with a chamber 20, which
includes a top wall 22, two side walls 24 bending downward from two
sides of the top wall 22 respectively, and a bottom walls 26
further bending from each of the two side walls 24 of the shielding
cover 2. A plurality of projected latches 21 and a plurality of
corresponding recessed latches 23 are formed at ends of the two
bottom walls 26 respectively, these recessed latches 23 and
projected latches 21 are correspondingly latched to prevent the two
bottom walls 26 from sliding forward and backward with respect to
each other. The top wall 22 and the bottom walls 26 of the
shielding cover 2 are formed with two latching claws 28,
respectively, the latching claws 28 may correspondingly latch with
a corresponding mating electrical connector 10 (see FIG. 4),
thereby obtaining a steady engagement. The sidewalls 24 of the
shielding cover 2 extend downward with two pairs of joint legs 30
to be correspondingly soldered to a circuit board 8. Wherein two
pairs of bending and transition portions 32 in an identical
configuration and in a symmetric structure are formed on each of
the two side walls 24 and extends to the bottom walls 26 of the
shielding cover 2. A latching arm 34 extends backward from each of
the two sidewalls 24 of the shielding cover 2 (note: the shape of
the latching arms 34 shown in the drawings is the shape it forms
after being bent after insertion of the dielectric housing 4). A
front end of the top wall 22 of the shielding cover 2 extends
upward to form a fixing plate 36, and a fixing hole 38 is defined
in the fixing plate 36.
[0018] The dielectric housing 4 includes a vertical wall 43, a
bottom plate 41 extending forward from the vertical wall 43, and a
separate terminal locating plate 45 extending forward from a middle
portion of the vertical wall 43 and spaced apart from and generally
parallel to the bottom plate 41. The separate plate 45 may be
received in the chamber 20 of the shielding cover 2, and the upper
and lower surfaces of the separate plate 45 define a plurality of
receiving slots 42 for receiving the conductive terminals 6. Two
sides 41 a, 41b of the bottom plate 41 of the dielectric housing 4
project upward with two support portions 44 in shapes corresponding
to the bending and transition portions 32, and the two support
portions 44 each may be inserted between the joint leg 30 and the
bending and transition portion 32 of the shielding cover 2, for
supporting the bending and transition portion 32 from below to
prevent it from being deformed. Two sides of the vertical wall 43
of the dielectric housing 2 further define a latching slot 46,
respectively, and the latching arms 34 of the shielding cover 2 may
be latched with corresponding latching slots 46 of the vertical
wall 43 for fixing the dielectric housing 4 to the shielding cover
2.
[0019] During assembly, the conductive terminals 6 are firstly
inserted into corresponding receiving slots 42 of the dielectric
housing 4, then the dielectric housing 4 is mounted on the
shielding cover 2, so that the two support portions 44 thereof
support the bending and transition portions 32 of the shielding
cover 2 from below, thereby preventing the bending and transition
portions 32 from being deformed. Finally the latching arms 34 of
the shielding cover 2 are punched and bent, so that they are
assembled with the latching slots 46 of the vertical wall 43 for
fixing the dielectric housing 4 to the shielding cover 2.
[0020] Because the two pairs of bending and transition portions 32
of the shielding cover 2 are identical, they can be formed in a
single bending operation as compared to the prior art shielding
cover that required two bending operations to form the two
different pairs of bending and transition portions 108 and 110.
Furthermore, the bending and transition portions 32 are protected
from being deformed after repeated insertions and withdrawals due
to the two support portions 44 of the dielectric housing 4
supporting the bending and transition portions 32 from the
below.
[0021] While a preferred embodiment of the present invention is
shown and described, it is envisioned that those skilled in the art
may devise various modifications of the present invention without
departing from the spirit and scope of the appended claims.
